Résumé

The time course of colored dissolved organic matter (CDOM) absorption and fluorescence were monitored during 50 to 70 days of laboratory incubations with water collected in the coastal upwelling system of the Ria de Vigo (NW Iberian Peninsula) under contrasting hydrographic conditions. CDOM fluorescence at peak-T (Ex/Em, 280/350 nm), characteristic of protein-like materials, decayed at a 1st order degradation rate constant (k(T)) of 0.28 +/- 0.13 day(-1) (average +/- SD). k(T) covaried (R-2 = 0.86, p
